Sex Differences In Copd And Lung Cancer Mortality Trends—United States, 1968–1999, Neely Kazerouni, C. J. Alverson, Stephen C. Redd, Joshua A. Mott, David M. Mannino

David M. Mannino

Purpose: Cigarette smoking by U.S. women in the 1940s and 1950s caused large increases in smoking-related lung disease among women. To determine the magnitude of these increases, we compared the mortality trends for males and females in the United States for chronic obstructive pulmonary disease (COPD) and lung cancer for 1968-1999.

Methods: We used the national mortality data files compiled by the National Center for Health Statistics of the CDC and U.S. census data to calculate age-adjusted (2000) death rates for COPD, lung cancer, and all causes.

Results: COPD death rate for females increased by 382% from 1968 through 1999, …

Investigation Of Clusters Of Giardiasis Using Gis And A Spatial Scan Statistic., Agricola Odoi, S W. Martin, P Michel, D Middleton, J Holt, J Wilson Jun 2004

Investigation Of Clusters Of Giardiasis Using Gis And A Spatial Scan Statistic., Agricola Odoi, S W. Martin, P Michel, D Middleton, J Holt, J Wilson

Agricola Odoi

BACKGROUND: Giardia lamblia is the most frequently identified human intestinal parasite in Canada with prevalence estimates of 4-10%. However, infection rates vary by geographical area and localized 'pockets' of high or low infection rates are thought to exist. Water-borne transmission is one of the major routes of infection. Sources of contamination of drinking water include humans, domestic and wild animals. A previous study in southern Ontario, Canada, indicated a bivariate association between giardiasis rates and livestock density and/or manure use on agricultural land; however these variables were not significant when the variable 'rural' was added to the model. In that …


Risk Factors For Asthma Incidence: A Review Of Recent Prospective Evidence, M. S. King, David M. Mannino, F. Holguin Jun 2004

Risk Factors For Asthma Incidence: A Review Of Recent Prospective Evidence, M. S. King, David M. Mannino, F. Holguin

David M. Mannino

AIM:

The aim of this study is to determine what factors have been shown, in prospective studies, to predict the incidence of asthma.

METHODS:

We performed a systematic review of peer-reviewed literature from 1994 to 2004 to determine what factors predict the development of asthma in both children and adults. This search strategy yielded 40 studies, with 36 providing some estimate of asthma incidence for the total sample and or a specific subgroup.

RESULTS:

Annual estimated incidence of physician-diagnosed asthma ranged from 0.6 to 29.5 per 1000 persons. Risk factors for incident asthma among children included: male sex, atopic sensitization, …


The Late Effects Of Poliomyelitis In Queensland, Mary Lynch, Nancy Low Choy May 2004

The Late Effects Of Poliomyelitis In Queensland, Mary Lynch, Nancy Low Choy

Nancy Low Choy

This paper reports an investigation of new health problems reported by Queensland residents with a prior history of poliomyelitis. 126 people with a past history of paralytic poliomyelitis were recruited from the waiting list for the trial Post Polio Clinic at Queen Elizabeth II Hospital, Brisbane. A self-administered postal questionnaire was used to examine a number of variables including acute poliomyelitis histories; presence, duration and severity of new symptoms consistent with the late effects of poliomyelitis; changes in functional status between the maximal recovery period and the time of the survey and the impact of post-polio symptoms on lifestyle and …


Prediction Of Radiation Pneumonitis By Dose-Volume Histogram Parameters In Lung Cancer--A Systematic Review, George Rodrigues, Michael Lock, David D'Souza, Edward Yu, Jake Van Dyk Apr 2004

Prediction Of Radiation Pneumonitis By Dose-Volume Histogram Parameters In Lung Cancer--A Systematic Review, George Rodrigues, Michael Lock, David D'Souza, Edward Yu, Jake Van Dyk

Edward Yu

BACKGROUND AND PURPOSE: To perform a systematic review of the predictive ability of various dose-volume histogram (DVH) parameters (V(dose), mean lung dose (MLD), and normal tissue complication probability (NTCP)) in the incidence of radiation pneumonitis (RP) caused by external-beam radiation therapy. METHODS AND MATERIALS: Studies assessing the relationship between CT-based DVH reduction parameters and RP rate in radically treated lung cancer were eligible for the review. Synonyms for RP, lung cancer, DVH and its associated parameters (NTCP, V(20), V(30), MLD) were combined in a search strategy involving electronic databases, secondary reference searching, and consultation with experts. Individual or group data …


Impaired Diffusion Capacity Predicts For Decreased Treatment Tolerance And Survival In Limited Stage Small Cell Lung Cancer Patients Treated With Concurrent Chemoradiation, Gregory Videtic, Larry Stitt, Robert Ash, Pauline Truong, A. Dar, Edward Yu, Frances Whiston Jan 2004

Impaired Diffusion Capacity Predicts For Decreased Treatment Tolerance And Survival In Limited Stage Small Cell Lung Cancer Patients Treated With Concurrent Chemoradiation, Gregory Videtic, Larry Stitt, Robert Ash, Pauline Truong, A. Dar, Edward Yu, Frances Whiston

Edward Yu

PURPOSE: To determine if stratification of limited stage small cell lung cancer (LSCLC) patients by pre-treatment pulmonary function test (PFT) prognostic indicators predicts for treatment-related toxicity risks and survival following concurrent chemoradiation. MATERIALS AND METHODS: From 1989 to 1999, 215 LSCLC patients received six cycles of alternating cyclophosphamide/doxorubicin/vincristine and etoposide/cisplatin (EP). Thoracic radiation (RT) was initiated only with EP and at cycle 2 or 3. RT dose was: 40 Gy/15 fractions/3 weeks or 50 Gy/25 fractions/5 weeks. RT fields encompassed gross and suspected microscopic disease with a 2 cm margin. Pre-treatment PFT values analyzed included forced expiratory volume in 1s …


Stroke Mortality In Sao Paulo (1997-2003). A Description Using The Tenth Revision Of The International Classification Of Diseases, Paulo A. Lotufo Jan 2004

Stroke Mortality In Sao Paulo (1997-2003). A Description Using The Tenth Revision Of The International Classification Of Diseases, Paulo A. Lotufo

Paulo A Lotufo

Stroke mortality rates are higher in Brazil when compared to other countries. The city of Sao Paulo has a good system of mortality surveillance that allow us to describe the epidemiology of the stroke in the city. Our aim was to describe the stroke mortality pattern by gender and age characterizing the ischemic/hemorrhagic ratio. We categorized mortality data by gender and a 10-year age-strata from 30-39 years-old to 70-79 years-old. To avoid random variations, we calculated the mean of all deaths occurred during the period of 1997 to 2003. Mortality rates were calculated using the population from the Brazilian National …

Ensuring The Comparability Of Comparison Groups: Is Randomization Enough?, Vance Berger, Sherri Rose Dec 2003

Ensuring The Comparability Of Comparison Groups: Is Randomization Enough?, Vance Berger, Sherri Rose

Sherri Rose

It is widely believed that baseline imbalances in randomized trials must necessarily be random. In fact, there is a type of selection bias that can cause substantial, systematic and reproducible baseline imbalances of prognostic covariates even in properly randomized trials. It is possible, given complete data, to quantify both the susceptibility of a given trial to this type of selection bias and the extent to which selection bias appears to have caused either observable or unobservable baseline imbalances. Yet, in articles reporting on randomized trials, it is uncommon to find either these assessments or the information that would enable a …
